Sorry, I may be a bit dense, but I don't get how to apply your instructions. I'll try to comment inline:

  % mkdir /Volumes/GRML

Got it, create the mountpoint

  % sudo mount_cd9660 /dev/disk2s1 /Volumes/GRML

Here's where you lost me, /dev/disk2s1 is anything, but not the grml.iso image that is lying in my ~/Downloads/ folder. How do you propose I get the disk subsystem to recognize that it should be attached as a device on /dev/disk2s1?

  % cp -a /Volumes/GRML/* /Volumes/GRMLFOR64/
  % diskutil unmount /Volumes/GRMLFOR64/
  % sudo umount /Volumes/GRML
  % sudo umount /Volumes/GRML

The rest I get, but haven't tried yet. Just out of curiosity, what is the benefit of this method vs. the method the ubuntu guys propose? Their proposal did work for me to get the USB-Stick to boot.

Regards,
Martin
